Unitary Products Group

FEATURES

All models are available with a wide variety of factory-
mounted options such as stainless steel heat exchangers, 
electric heaters, phase monitor, convenience outlet, dirty filter 
switch, disconnect switch, smoke detectors, and coil guard to 
make them suitable for almost every application.

All units are self-contained and assembled on full perimeter 
base rails with forklift holes on three sides and holes for over-
head rigging. Every unit is completely piped, wired, charged 
and tested at the factory to simplify the field installation and to 
provide years of dependable operation.

All models (including those with an economizer) are suitable 
for either bottom or horizontal duct connections. For bottom 
duct, remove the sheet metal panels from the supply and 
return air openings through the base of the unit. For horizon-
tal duct, remove the supply and return air panels on the rear 
of the unit.

All models are available with these “factory mounted” outdoor 
air damper options:

Single enthalpy economizer

Motorized outdoor air damper

Supply air blowers are equipped with either a direct drive or a 
belt drive that can be adjusted to meet the exact require-
ments of the job.

All compressors are equipped with internal pressure relief. 
Every refrigerant circuit includes a liquid line filter-drier, a high 
pressure switch and a suction line with a freezestat and low 
pressure/loss of charge switch to protect all system compo-
nents.

 Controls - 

Simplicity

®

 control boards have 

standardized a number of features previously available 
only as options or by utilizing additional controls.

Low Ambient 

- An integrated low-ambient control 

allows all units to operate in the cooling mode down 
to 0ºF outdoor ambient without additional assis-
tance. Optionally, the control board can be pro-
grammed to lockout the compressors when the 
outdoor air temperature is low or when free cooling 
is available.

Anti-Short Cycle Protection

 - To aid compressor 

life, an anti-short cycle delay is incorporated into the 
standard controls. Compressor reliability is further 
ensured by programmable minimum run times. For 
testing, the anti short cycle delay can be temporarily 
overridden with the push of a button.

Fan Delays

 - Fan on and fan off delays are fully pro-

grammable and are independent of one another. All 
units are programmed with default values based 
upon their configuration of cooling and heat.

Safety Monitoring

 - The control board monitors the 

high and low-pressure switches, the freezestats, the 

gas valve, if applicable, and the temperature limit 
switch on gas heat units. The unit control board will 
alarm on ignition failures, compressor lockouts and 
repeated limit switch trips.

Nuisance Trip Protection

- To prevent nuisance 

trouble calls, the control board uses a “three strikes, 
you’re out” philosophy. The high and low-pressure 
switches and the freezestats must trip three times 
within two hours before the unit control board will 
lock out the compressor.

On Board Diagnostics

 - Each alarm will energize a 

trouble light on the thermostat, if so equipped, and 
flash an alarm code on the control board LED. Each 
high and low-pressure switch alarm as well as each 
freezestat alarm has its own flash code. The control 
board saves the five most recent alarms in memory, 
and these alarms can be reviewed at any time. 
Alarms and programmed values are retained 
through the loss of power.

All units have long lasting powder paint cabinets with 1000 
hour salt spray test approval under ASTM-B117 procedures.

All models are CSA listed.

Warranty

 - All models include a one-year limited parts 

warranty on the complete unit. Compressors and electric 
heater elements carry a five-year warranty. Gas heat 
exchangers carry a 10-year parts warranty.

Gas Heat Operation 

- All single phase models with gas 

heat have minimum annual fuel utilization efficiency 
(AFUE) of 80%. All three phase models with gas heat 
have minimum steady state efficiency of 80%. Each sec-
tion includes a durable heat exchanger with aluminized 
steel or optional stainless steel tubes, a redundant gas 
valve, spark ignition, power venting, an ignition module for 
100% shut-off and all of the safety controls required to 
meet the latest ANSI standards.

The gas supply piping can be routed into the heating 
compartment through a hole in the base pan of the unit 
or through a knockout in the piping panel on the front of 
the unit.

Electric Heat Operation

 - All electric heat models are 

wired for a single power source and include a bank of 
nickel chromium elements mounted at the discharge of 
the supply air blower to provide a high velocity and uni-
form distribution of air across the heating elements. 
Every element is fully protected against excessive tem-
perature by thermal limit switches.

The power supply wiring can be routed into the control 
box through a threaded pipe connection (field supplied) 
in the base pan of the unit or through a knockout in the 
wiring panel on the side of the unit.

BAS Controls

 - York’s Sunline™ series units offer factory 

mounted BAS controls such as
